Last year in a group of 30 businesses, 21 reported a net profit and
15 had investments in foreign markets. How many of the businesses
did not report a net profit nor invest in foreign markets last year?
(1) last year 12 of the 30 businesses
reported a net profit and had investments
in foreign markets.
(2) last year 24 of the 30 businesses
reported a net profit or invested in
foreign markets, or both.

IMO Ans D

Suppose N buss reported net profit, I had investment and NI had both

As per question
N+NI = 21 ----- (1)
I+NI = 15 ----- (2)

Stmt 1 => NI = 12
Only N = 21-12 = 9
Only I = 15-12 = 3

Buss that have no profit no investment = 30 - (12 + 9+ 3) = 6

Stmt 2
N + I + NI = 24

Buss with no profit no investment = 30 - 24 = 6
